Sewing Machine Repair Man coming to STX

Hey there, I plan on moving to STX sometime around April with my better 3/4's. Sewing Machine Repair is what I do and I would like to gauge how much of a need there is for this service and to ask what else I could do for all you fine islanders.

Is there much of a need for sharpening services for example? I see from the forum that belts need replacing often, any other parts like that? I imagine there are a lot of vintage machines (my fav) since they last forever.

Looking forward to your valuable input! I aim to please and shoot for making a machine run as good as new whenever possible.

Cheers!
